Title: Method for leading in focusing servo
Inventor: YAMAGUCHI EIJI
IPC: G11B7/085
Filed: 1987-08-03
Abstract: PURPOSE:To confirm that a servo lead-in is correctly executed by calculating a difference between the detecting value of an optical movable part position and the optical movable part position at the time of focusing for a proper time at the time of leading in a focusing servo and deciding a normal focusing condition by the fact that the calculating value is in a prescribed range. CONSTITUTION:The optical movable part position in a focusing direction to an optical head main body is detected beforehand. From the time when the detecting value of a medium reflecting light in an optical head 18 is in the prescribed range, the difference between the detecting value of the optical movable part position and the optical movable part position detecting value at the time of focusing is calculated for the proper time, the normal focusing condition is decided by that the calculating value is in the prescribed range, and the servo lead-in is completed. Namely, by monitoring the difference between a position detecting signal value and the value of the focusing time position for a fixed time, a transfer phenomenon at the time of closing a focusing servo loop is waited for until it goes static, and further, a servo lead-in completion is prevented from being decided, by mistake, to be correct only by an instantaneous focusing condition. Thus, at the time of leading in the focusing servo, it can be confirmed that the lead-in is correctly executed.

Title: Axial flow type laser oscillator
Inventor: NAWA AKIYOSHI
IPC: H01S3/036
Filed: 1986-08-19
Abstract: PURPOSE:To obtain a stable laser oscillator, in which the effect of thermal expansion can be removed, by the constitution, wherein any one block of a plurality of blocks constituting the oscillator is fixed on a base table, and the other blocks are arranged in a free state. CONSTITUTION:Only a block 26 provided with a partial reflecting mirror 9 is fixed on a base table 1. Other blocks 2a and 2c are arranged in space in a free state. Namely, a pair of supporting shafts 10 and 10 are extended from the inside of the fixed block 2b in the horizontal direction. The block 2a having a total reflecting mirror 8 is arranged at the extended ends of the shafts 10. At the center between the block 2a and the fixed block 2b, the block 2c, to which a laser gas exhaust pipe 5 is connected, is arranged. Since only the block 2b having the partial reflecting mirror 9 is fixed to the base table 1 and the other blocks are not physically constrained at all, the sizes can be freely changed in response to thermal expansion. Therefore sliding is not yielded between the blocks 2a, 2b and 2c and the supporting shafts 10, and alignment between a resonator and discharge electrodes 3 and 3 can be maintained.
